Answer:
see below
Step-by-step explanation:
The recursive function tells you the first term is 1. That is the meaning of ...
It also tells you that to find the next term, you multiply this term by 1/2:
And, to find the next term, you multiply this term by 1/2:
Then the first three terms are ...
1, 1/2, 1/4
Check the picture below.
you can pretty much just count off the grid the units for JK and MI.
now, let's check how long are KI and JM

so, add all sides, and that's the perimeter of the trapezoid.
